('64 Code, Sec. 34-36.3) (Ord. No. 1373)
(2) R-1 lot requirements.
(a) Minimum lot area. Every newly created lot shall have a lot area of not less than 6,000 square feet.
(b) Minimum lot frontage. The frontage measured at the front lot line shall be at least 50 feet. Frontage for this purpose shall be defined as the linear measurement between the two side property lines at their point of tangency with the curb.
(c) Minimum lot dimensions.
1. Interior lots shall be no less than 60 feet in width.
2. Corner lots shall be no less than 75 feet in width.
3. The depth of a lot shall be at least 100 feet.
(3) R-1 front yard.
(a) There shall be a front yard setback of not less than 20 feet; except that houses constructed with garages having a swing driveway, with the entrance facing the side property line, may have a minimum 15-foot setback. Where standard dwellings within any block vary from the required setback, the average setback of such standard dwellings shall determine the required setback within that block if the standard dwellings comprise at least 60% of the block.
(b) In calculating the average setback, houses on reverse corner lots and houses wholly on the rear half of the lot shall not be counted. In no case shall setbacks of less than 15 feet be allowed, or setbacks of more than 60 feet be required.
(c) There shall be a distance of not less than 20 feet, measured at the center line of the driveway, between the garage door and the front property line.

(b) On corner lots the side yard regulation shall be the same as for the interior lots except in the case of a reversed corner lot. In the case of a reversed corner lot, there shall be a side yard on the street side of the corner lot of not less than 50% of the front yard required on the lots in the rear of such corner lot, and no accessory building on the corner lot shall project beyond the front yard line on the lots in the rear; provided further that this regulation shall not be so interpreted as to reduce the buildable width (after providing the required interior side yard) of a reversed corner lot of record on March 29, 1945, to less than 28 feet, nor to prohibit the erection of an accessory building where this regulation cannot reasonably be complied with.
('64 Code, Sec. 34-41) (Ord. No. 893, 1019)

('64 Code, Sec. 34-42.2) (Ord. No. 1409, 1611)
(B) R-2 zone.
(1) R-2 density. There shall be at least 3,500 square feet of lot area for each dwelling unit. No more than one dwelling unit may be constructed on any lot with an average width of less than 50 feet or with an area less than 7,000 square feet.

(a) There shall be a front yard of not less than 25% of the depth of the lot, provided such front yard need not exceed 25 feet. Where standard dwellings within any block vary from the required setback, the average of such standard dwellings shall determine the required setback for that block if such standard dwellings comprise at least 60% of the block. In calculating such average setback, houses on reversed corner lots and houses wholly on the rear half of a lot shall not be counted.
(b) In no case shall setbacks of less than 25 feet be allowed, or more than 60 feet be required. Where six or more dwellings are to be built concurrently within a given block, front yards of that block may average a minimum of 20 feet, provided houses within each block are staggered between 15 to 25 feet, and provided further that there shall be a distance of not less than 20 feet measured at the center line of the driveway between the garage door and the front property line.

This regulation shall not be interpreted to reduce the buildable width (after providing the required interior side yard) of a reversed corner lot of record on March 29, 1945, to less than 25 feet, nor to prohibit the erection of an accessory building where this regulation cannot reasonably be complied with.
